To all wlmin il may concern.' Be it known that I, Josiir 'rt LisoH, a.citizen of the Republic of b`witzerland, residing at Zurich, inSwitcrl-aiid, have invented new and useful Imp oi'eincnts inBall-Bearings, of which the following is a specification.

he present. invention relates to certain new and useful iinprovci'nentsin ball bear` ings, and more especially to a new construction ofball-races for bearings of that type in which two concentrical rines areprovided in their facing surfaces wit i grooves which serve as races forthe balls, and in which between eaeh two main or ruiming balls there isinterposed a spacing ball, the diameter of which is smaller than thatofthe ruiming balls, but larger than the distance between the faein edgesof the conceutrical rings.

According to the present invention, Ione of the edges in one of therings, in order to introduee the spacing balls into the raices betweenthe lar e'balls is in the form of an,

easily reniova to preventthe sidcwise. For intro( ucing' these balls,the separable ring, of course, must first be removed.

In the accom le ring of such dimensions as panying drawing Figure lrepresents a sido elevation Fig. 2 a vertical section through a bearing.

a and b are the two conentrical rings c the grooves therein, d therunninv balls, sindfthe spacing halls. T hese latter ave a diameterwhich is smaller than that of 'the balls :[,but

larger than the distance :c between the facing' The distance bel facesforming a raceway be edges of the rings aand b.V

two rings may be contracted on one side by means of a re movable ring g,so fitted that this ring will readily retain its position within therings a, b without iinv special securing means. It desired this ringnmv,' however, also be securet by any suitable means that will of itseasy removal. For the purpose of introducing the s )seing balls, thering g is removed, tlie bal s are inserted, and the ring then put inagain. The ringg is also of such dimension that when 4this ring isremoved, the running balls cannot be introduced between the concentricalrines a, b.

To assemble the spacing balls from falling out parts t ie ring b ispla-ccd' i l i permit. i.

within the ring a eeccntriciilly, or so that at one point the ring btouches tiie inner face of ring a. Diainetriciilli' opposite this pointthe space between the two rings will be much greater than when the partsare assembled, so that the hiiiin or running balls d. can The balls diire'theu distributed around tie'rsceway and the inner ring b movedinl-o position concentric with the outer ring. The spacing ballsf arethen dropped into plnce between the mein bulls und liniilly the ring gissprung into place.

Having now particularlyv rertiiincd the nature of th end in what mannerthe formed, I declare that what I claim is:

1. A ball bearing comprising two concen tric continuous Viings havinggiooved faces coperating to forni a' bell race-wey betweenthe11i,riiiining balls and spacing balls in the raceway, the distancebetween the facing edges of the rings on one side being greater than onthe other, the edges on one side of the rings having the lesserdistance, between them, retaining both the running and the s acing ballsin the receive-y, and the edges of the other side of the rings retainingthe running balls, and a spacimr out of contact with the caring bullsbeyond the bearing surfaceof the raceway and secured to one of saidrings within the space iaving the greater distance between the facing edes.

2. ball bearing comprising two concentric continuous rings havingsimilar grooved tween them, running balls and spacing balls in theracewsg', the distance between the facing ed es'of t o rings when' inconcentric posit-ion Eeing than the .diameter of the running balls saidedges retaining them in the raceway, and a locking ring at one sideofthe bearin surface of the iaeeway forming the edge di one of describedandase sind inventi n same is to be 'pier-l5 I "in i ball retaining ringles.

3.
